The following source codes have been added to the Description Convention Source Codes list for usage in appropriate fields and elements.

The question of how to integrate the multitude of national online resources needs to be considered, how they should be catalogued, how they should be made accessible, and how they could be discovered by bibliography users. Because the Working Group on Guidelines for National Bibliographies of the IFLA Bibliography Section was concerned with exactly these „new directions”, we decided to build our guidelines on their recommendations, published in 2009 under the title National Bibliographies in the Digital Age: Guidance and New Directions. Our guidelines can be understood as a supplement to the 2009 Guidelines.

Our work is also an appeal to the producers of national bibliographies to provide subject access in national bibliographies. Users will benefit from using well organized subject structures of classification systems and subject headings to expand their ways of reaching the resources they want.
